I intend to make a mail proxy to receive mails
of 2 different domains :
oldDomain.com.br (configured in my old Bm 3.5)
and newDomain.com.br

Mail proxy is configured as follwed:
Primary Mail Domain Name : mail.oldDomain.com.br
Internal Mail Server Name : mail.lyceepasteur.org

Here is part of my PROXY.CFG:
[Extra Configuration]
ProcessMultipleMXRecordsOfDomain=1
[Multiple Domain Support]
MultiDomain1=mail.lyceepasteur.org/newDomain.com.br
MultiDomain2=mail.lyceepasteur.org/oldDomain.com.br
[BM Mail Proxy]
BM_Domain=oldDomain.com.br
BM_Proxy_Domain=mail.oldDomain.com.br
BM_Incoming_Relay=0

Obs: lyceepasteur.org is my internal domain name.


When I send an email to an address of my old Domain
I receive an OK (250) :
telnet mail.oldDomain.com.br 25
220 Service ready
helo externalDomain
250 oldDomain.com.br OK
mail from:<eric@externalDomain>
250 OK Requested mail action completed
rcpt to:<informatique@oldDomain.com.br>
250 OK Requested mail action completed


When I send an email to an address of my new Domain
I receive a Syntax error (501)
telnet mail.newDomain.com.br 25
220 Service ready
helo externalDomain
250 oldDomain.com.br OK
mail from:<eric@externalDomain>
250 OK Requested mail action completed
rcpt to:<informatique@newDomain.com.br>
501 Command syntax error


Have I forgotten something ?

TIA
Eric.
